lüll Small mitochondria-targeting molecules as anti-cancer agents Wang F; Ogasawara MA; Huang PMol Aspects Med 2010[Feb]; 31 (1): 75-92Alterations in mitochondrial structure and functions have long been observed in cancer cells. Targeting mitochondria as a cancer therapeutic strategy has gained momentum in the recent years. The signaling pathways that govern mitochondrial function, apoptosis and molecules that affect mitochondrial integrity and cell viability have been important topics of the recent review in the literature. In this article, we first briefly summarize the rationale and biological basis for developing mitochondrial-targeted compounds as potential anti-cancer agents, and then provide key examples of small molecules that either directly impact mitochondria or functionally affect the metabolic alterations in cancer cells with mitochondrial dysfunction. The main focus is on the small molecular weight compounds with potential applications in cancer treatment. We also summarize information on the drug developmental stages of the key mitochondria-targeted compounds and their clinical trial status. The advantages and potential shortcomings of targeting the mitochondria for cancer treatment are also discussed.|Animals[MESH]|Antineoplastic Agents/*pharmacology[MESH]|Apoptosis/drug effects[MESH]|DNA, Mitochondrial/drug effects/genetics[MESH]|Drug Delivery Systems/*methods[MESH]|Glycolysis/drug effects[MESH]|Humans[MESH]|Mitochondria/*drug effects/genetics/metabolism[MESH]|Neoplasms/drug therapy/genetics/metabolism[MESH]|Reactive Oxygen Species/metabolism[MESH] |
